The LCM of 380,546,970,741 is 10062780.
Find LCM of 380,546,970,741 with Prime Factorization
| 2 | 380, 546, 970, 741 |
| 3 | 190, 273, 485, 741 |
| 5 | 190, 91, 485, 247 |
| 13 | 38, 91, 97, 247 |
| 19 | 38, 7, 97, 19 |
| 2, 7, 97, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 19 x 2 x 7 x 97 x 1 = 10062780
Therefore, the lowest common multiple of 380,546,970,741 is 10062780.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
380 x 546 x 970 x 741 = 149130399600
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
970 : 1, 2, 5, 10, 97, 194, 485, 970
741 : 1, 3, 13, 19, 39, 57, 247, 741
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,546,970,741, is 1.
Now, the common factors can be found like this.
380:2x 2x 5x 19
546:2x 3x 7x 13
970:2x 5x 97
741:3x 13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 5x 13x 19 = 14820
Therefore, the value for common factors is 14820.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 149130399600/(1x14820)
LCM = 149130399600/14820
LCM = 10062780
Thus, we can understand that the LCM of 380,546,970,741 is 10062780.
